Answer:
x = 17/3
Step-by-step explanation:
3(2x - 3) + x = 4(x + 2)
7x - 9 = 4x + 8
Add 9 to both sides:
7x - 9 + 9 = 4x + 8 + 9
Simplify:
7x = 4x + 17
Subtract 4x from both sides:
7x - 4x = 4x + 17 - 4x
Simplify:
3x = 17
Divide both sides by 3:
3x/3 = 17/3
x = 17/3
Hope this helps!!
R - 5 1/6 = 10
r - 31/6 = 10
+ 31/6 +31/6
r = 91/6
So, r = 91/6.
And, I am not sure if the second one I am doing in right or wrong, but I am just guessing.
I think you use substitution method here.
8(x-2)+9 = 14
8x-16+9 = 14
8x-7 = 14
+7 +7
8x = 21
x = 21/8
So, the answer is 21/8
HOPE THID HELPS AND I REALLY HOPE THAT THE SECOND ANSWER IS RIGHT!!!!!!
