Answer: a=2.72
Explanation:
Move all the terms containing a to the left side of the equation
-0.5a+4.96=3.6
Subtract 4.96 from right side
-0.5a=3.6-4.96
Would be
-0.5a=-1.36
Divide each term by -0.5 and simplify
a= 2.72
Y = 3
Explanation:
5y - 7 = 3y - 1
5y - 3y = - 1 + 7
2y = 6
y = 3
The number would be 5. 5 divided by 5 equals 1. Then 1-12 would be -11 and then you do -11 times 5 which gives you -55!
