-2x +7 = 3x - 8
Move the variable to the left-hand side and change its sign
-2x -3x+ 7 = -8
Move the constant to the right-hand side and change its sign
-2x -3x = -8 -7
Collect like terms
-5x = -15
Divide both sides of the equation by -5
x=3
The answer is D hope this helps
Answer:
yes
Step-by-step explanation:
Given the 2 equations
y =
x + 6 → (1)
y = -
x + 5 → (2)
Substitute y =
x + 6 into (2)
x + 6 = -
x + 5 ( add
to both sides )
x + 6 = 5 ( subtract 6 from both sides )
x = - 1 ( divide both sides by
)
x =
= -
← one solution
