If 5x + 8 = -7 then x = -3 ! -3 x 5 = -15 -15 + 8 = -7 !
5x=4012y=84124
The answer is -8.
If: 3x+8-x = 5x-4 Then: x = 4
5x+y=-7 3x+y=15 8=D
If 5x + 8 = -7 then x = -3 ! -3 x 5 = -15 -15 + 8 = -7 !
5x=4012y=84124
The answer is -8.
x=-3
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
If: 3x+8-x = 5x-4 Then: x = 4
5x+y=-7 3x+y=15 8=D
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
27 - 5x = -8Add 5x to each side:27 = -8 + 5xAdd 8 to each side:35 = 5xDivide each side by 5:7 = x
if it is 5x + 8 = 23 then the answer is 3. if it is 5x - 8 = 23 then the answer is 31/5.
4x-7=5x-2 x=-5
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
