Make a the subject of the formula: t=a+4

Let's solve for a.

t=a+4

Step 1: Flip the equation.

a+4=t

Step 2: Add -4 to both sides.

a + 4 + −4 = t + −4

a=t−4

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
