Firstly , Let Rebecca age be R and Steve age be S

Steve is 6 years younger than twice Rebecca age

Since steve is younger, then we will be using subtraction as the order of operation

Since Rebecca age is twice

Then, R x 2

=2R

Steve is 6 years younger than twice of Rebecca age

Mathematically ,

S=-2R - 6  ---------------- equation 1

the sum of Steven and Rebecca age is 30

R+S =30------------------ equation 2

Solve equation 1 and equation 2 simultaneously

S=2R-6\\S+R=30

Substitute S=2R-6 into equation 2

2R-6+R=30

Collect like terms

2R+R=30-6

3R=36

Divide both sides by R

\frac{3R}{3} =\frac{36}{3\\} \\R=12

On the Algebra test the number of students who got a grade A was three more than twice the number of students who got lower grad
svlad2 [7]
X= # students who got lower grades
2x+3= # students with grade A

STEP 1:
Add the two sets above equal to 24.

x + (2x + 3)= 24
combine like terms

3x + 3= 24
subtract 3 from both sides

3x= 21
divide both sides by 3

x= 7 (# students lower than A)


STEP 2:
substitute x value from step 1 to find # grade A students

=2x + 3
=2(7) + 3
=14 + 3
=17 (# grade A students)


CHECK:
x + (2x + 3)= 24
7 + 2(7) + 3= 24
7 + 14 + 3= 24
24= 24


ANSWER: There were 17 students with grade A.

Hope this helps! :)
