Answer:
X = -3
Step-by-step explanation:
5x - 2x +7 = x+1
3x + 7 = x+1
3x + 7 -7 = x+ 1 - 7
Simplify
(Subtract the numbers)
3x = x-6
Subtract x from both sides of the equation
3 x = x-6
3x - x = x -6 -x
Simplify
(Combine like terms)
2x = -6
Divide both sides of equations by same terms
2x = -6
2x/2 = -6/2
Simplify
(Cancel terms that are both in the numerator and denominator)
(Divide the numbers)
x = -3
