To solve these equations:
357 + y = 640Subtract 357 from both sides to isolate y:y = 640 - 357y = 283
4a = 836Divide both sides by 4 to solve for a:a = 836/4a = 209
c / 7 = 126Multiply both sides by 7 to solve for c:c = 126 * 7c = 882
Therefore, the solutions are:y = 283a = 209c = 882
To solve these equations:
357 + y = 640
Subtract 357 from both sides to isolate y:
y = 640 - 357
y = 283
4a = 836
Divide both sides by 4 to solve for a:
a = 836/4
a = 209
c / 7 = 126
Multiply both sides by 7 to solve for c:
c = 126 * 7
c = 882
Therefore, the solutions are:
y = 283
a = 209
c = 882
