Solution: x=7.6+2.4-5
x= 10-5
x=5
0.4(x+5)=2.4 fifth grade solution equation 0.4(x+5)= 2.4.
x+5=2.4÷0.4
x=6-5
x= 1
Solve the equation x÷5+6=2 1. The fifth grade math problem x÷5+6=2 1.
Solution:
x÷5=2 1-6
x÷5= 15
x= 15*5
x=75
Solve the equation! In the fifth grade of mathematics! (1) solution: x=22.4-8.8 (2) solution: x=6.84×3.8 (3) solution: 1.3x+2=28 (4) solution: 6x= 16.8.
x = 13.6 x = 25.922 1.3x = 26 x = 16.8÷6
x=26÷ 1.3 x=2.8
x=20
The fifth grade mathematics solves equation 7.4+x=6×5. 1.
7.4+x=30.6
x=30.6-7.4
x=23.2
25 x = 75÷5
25-x= 15
x=25- 15
x= 10
4(x- 17)= 1
4x-68= 1
4x= 1+68
4x=69
x= 17.25
12(x+ 1.2)= 144
x+ 1.2= 144÷ 12
x+ 1.2= 12
x= 12- 1.2
x= 10.8
52.6÷x+ 13+39.3
Where is the equal sign?
Assuming that there are x tons of grain each, press (x+32.5)=(x-32.5)*3.6.
So: 2.6x= 149.5, so x=57.5.
Namely: 57.5 tons for Party A and Party B respectively.
Solution: Suppose Xiaoyu picked x shells and Xiaoying picked 2.4x shells, that is, x+2.4x =173.4x =17x = 5a: Xiaoyu picked 5 shells and Xiaoying picked 12 shells.
Solution: First, circle 2.4 times in front of the insect specimen. This is the first unit, so set it as x, then set the previous plant specimen as 2.4X, and write an equal sign on the ratio, so add it because it is too much. It asks about the number of parts that need to be divided into two parts. Equivalence relation: number of plant specimens-number of insect specimens =49 Solution: There are x insect specimens and 2.4X plant specimens. Insect specimen: 2.4x-x = 491.4x = 491.4x ÷1.4 = 491.4x = 35 Plant specimen: 2.4X=35×2.4=84 A: This is a complete answer, and I have the skills to solve equations. I did it according to this technique. I got 100 in this exam, plus 10. I can get full marks by doing this, and I won't make mistakes step by step.
16 * 8-7X = 23 9X- 14 * 5.5 = 58
128-7x=23 9x-77=58
128=23+7x 9x=58+77
128-23=7x 9x= 135
105=7x x= 15
7x= 105
x= 15
