Write each of the following as an equation, and then solve for the variable.a. Four subtracted from z equals 12.b. If we increase t by 3, the result is 5.c. Seven multiplied by x equals 42.d. If we divide y by 4, the result is 12.e. A number n divided by 4 and increased by 8 equals 11.
What will be an ideal response?
a. z- 4 = 12
z- 4 + 4 = 12 + 4
z = 16
b. t + 3 = 5
t + 3 - 3 = 5 - 3
t = 2
c. 7x = 42
7x/7 = 42/7
x = 6
d. 
e.
