Answer:
x =
Step-by-step explanation:
Given
= - 4
Multiply both sides by 5
3ax - n = - 20 ( add n to both sides )
3ax = - 20 + n = n - 20
Isolate x by dividing both sides by 3a
x =
43/10 - 12/5x + 11/2 = 1/2(-18/5x + 6/5)
Do the stuff in parentheses first
43/10 - 12/5x + 11/2 = -9/5x + 3/5
Now we have to isolate the everything with an x in ine side, and the stuff without x (the variable) on the other
Do this by adding 12/5x to both sides of the equation to switch the -12/5x to the right side
43/10 - 12/5x + 12/5x + 11/2= -9/5x + 3/5 + 12/5x
43/10 + 11/2 = -9/5x + 3/5 + 12/5x
98/10 = 3/5x + 3/5
Now subtract both sides by 3/5 to switch the 3/5 to the left side
98/10 - 3/5 = 3/5x + 3/5 - 3/5
98/10 - 6/10 = 3/5x
3/5x = 92/10
Now divide both sides by 3/5
3/5x÷3/5 = 92/10 ÷ 3/5
x = (92×5)/(10×3)
x = 92/6
hope it helps, I double checked, it is correct.
