Ms. Irimie has 86 Academic Language of Math (ALM) and Algebra students in all. If 30 of her students are in the Algebra class, how many students are in the ALM class? WRITE an EQUATION to represent Ms. Irimie's total students, then solve for the variable.
30 + a = 86
a = 86 - 30
a = 56
Ms. Irimie has 56 students in the ALM class

Write an equation for:
the product of x and 12 is 48
12x = 48
100 = 56 + x
x = 44
x - 64=28
x = 92

Carl solves 3 times as many math problems as Allison. Together they solved 28 math problems. Write an equation to find how many math problems Carl and Allison each solved.
4x = 28
if Allison = x, Carl = 3x, so together x + 3x = 28, which is 4x = 28

Write an equation for:
24 is the difference between x and 7, increased by 13
x - 7 + 13 = 24
x + 6 = 24
