Answer:
-1
Step-by-step explanation:
Add '-7x' to each side of the equation.
4 + 3x + -7x = 8 + 7x + -7x
Combine like terms: 3x + -7x = -4x
4 + -4x = 8 + 7x + -7x
Combine like terms: 7x + -7x = 0
4 + -4x = 8 + 0
4 + -4x = 8
Add '-4' to each side of the equation.
4 + -4 + -4x = 8 + -4
Combine like terms: 4 + -4 = 0
0 + -4x = 8 + -4
-4x = 8 + -4
Combine like terms: 8 + -4 = 4
-4x = 4
Divide each side by '-4'.
x = -1
Simplifying
0
3x + 4 =7x + 8
group like terms:
3x - 7x = 8 - 4
step 2:
step 3:
-4x/-4 = 4/-4
therefore -4 will cancel -4 to remain the x :
x = 4/-4
which is equal as 0:
x =0
Let, Unknown number = x
8x-51 = 53
8x = 53+51
x = 104/8
x = 13
