Use the elimination method to solve:
a + c = 327
4a + 1.50c = 978
Check Format
Equation 1 is in the correct format.
Check Format
Equation 2 is in the correct format.
Step 1: Multiply Equation 1 by 4:
4 * (a+c=327) --> 4a + 4c = 1308
Step 2: Multiply Equation 2 by 1:
1 * (4a+1.50c=978) --> 4a + 1.5c = 978
Step 3: Equation 1 - Equation 2:
4a + 4c = 1308 - (4a + 1.5c = 978)
-(4a + 1.5c = 978)
4c - 1.5c = 1308 - 978
Step 4: simplify and solve for c:
2.5c = 330
c = 132
Step 5: Rearrange Equation 1 to solve for a:
1a = 327 - 1c
Divide each side by 1
Step 6: Plug c = 132 into equation 1:
a = 195
