2 answers:
Answer:
1
Step-by-step explanation:
Solve the equation for x:
3(x + 5) = -4x + 8
<em>Distribute.</em>
3x + 15 = -4x + 8
<em>Combine like terms.</em>
3x + 15 = -4x + 8
+4x +4x
7x + 15 = 8
-15 -15
7x = -7
<em>Divide both sides by 7.</em>
x = -1
The following equation has one solution, x = -1.
Answer:
1 solution, x = -1.
Step-by-step explanation:
3(x + 5 )= −4x + 8
3x + 15 = -4x + 8
3x + 4x = 8 - 15
7x = -7
x = -1.
