To solve the equation, we'll distribute the 3 on the left side and combine like terms:
3(-5x + 7) + 5/4 = -7x
-15x + 21 + 5/4 = -7x
Next, we'll combine the constant terms:
-15x + 21 + 5/4 = -7x
-15x + 5/4 = -7x - 21
Now, we'll combine the x terms:
-15x + 5/4 = -7x - 21
-15x + 7x + 5/4 = -21
-8x + 5/4 = -21
To isolate x, we'll subtract 5/4 from both sides:
-8x + 5/4 - 5/4 = -21 - 5/4
-8x = -21 - 5/4
-8x = -84/4 - 5/4
-8x = -89/4
Finally, we'll divide by -8:
x = (-89/4) / -8
x = 89/32
Therefore, the solution is x = 89/32.
Solve for x : 3(−5x+7)+5/ 4=−7x (1 point)
