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 = 202
Step 5: Rearrange Equation 1 to solve for a:
1a = 304 - 1s
Divide each side by 1
Step 6: Plug s = 202 into equation 1:
a = 102
