For the area you need the do length x width
Answer:
A:
Multiple: 3 * 5 = 15
Add: 7 + the result of step No. 1 = 7 + 15 = 22
Divide: 4 / 2 = 2
Subtract: the result of step No. 2 - the result of step No. 3 = 22 - 2 = 20
Add: the result of step No. 4 + 3 = 20 + 3 = 23
B:
Add: 7 + 3 = 10
Multiple: the result of step No. 1 * 5 = 10 * 5 = 50
Divide: 4 / 2 = 2
Subtract: the result of step No. 2 - the result of step No. 3 = 50 - 2 = 48
Add: the result of step No. 4 + 3 = 48 + 3 = 51
Simplify. Note the equal sign. What you do to one side, you do to the other. Follow PEMDAS.
Isolate the x.
First, distribute 6 to all terms within the parenthesis
6(-3) = -18
6(4x) = 24x
7x - 18 + 24x = 199
Simplify. Combine like terms
31x - 18 = 199
Isolate the x. Add 18 to both sides
31x - 18 (+18) = 199 (+18)
31x = 199 + 18
31x = 217
Isolate the x. Divide 31 from both sides
31x/31 = 217/31
x = 217/31
x = 7
7 is your answer for x
