Use the elimination method to solve:

a + s = 304

7a + 2s = 1118

Check Format

Equation 1 is in the correct format.

Check Format

Equation 2 is in the correct format.

Step 1: Multiply Equation 1 by 7:

7 * (a+s=304) --> 7a + 7s = 2128

Step 2: Multiply Equation 2 by 1:

1 * (7a+2s=1118) --> 7a + 2s = 1118

Step 3: Equation 1 - Equation 2:

7a + 7s = 2128 - (7a + 2s = 1118)
-(7a + 2s = 1118)

7s - 2s = 2128 - 1118

Step 4: simplify and solve for s:

5s = 1010

s  =  1010
  5

s = 202

Step 5: Rearrange Equation 1 to solve for a:

1a = 304 - 1s

Divide each side by 1

1a
1
=
  
304 - 1s
1

a  =  304 - 1s
  1

Step 6: Plug s = 202 into equation 1:

a  =  304 - 1(202)
  1

a  =  304 - 202
  1

a  =  102
  1

a = 102
