To solve these equations for a, c, and y, we will perform the necessary operations step by step:
700 - a = 400 - 160Subtract 400 from both sides:300 - a = -160Add a to both sides to solve for a:a = 300 + 160a = 460
90c = 430 - 250Subtract 250 from both sides:90c = 180Divide by 90 to solve for c:c = 180 / 90c = 2
y 10 = 840 - 290Subtract 290 from both sides:y 10 = 550Divide by 10 to solve for y:y = 550 / 10y = 55
Therefore, the solutions are:a = 460c = 2y = 55
To solve these equations for a, c, and y, we will perform the necessary operations step by step:
700 - a = 400 - 160
Subtract 400 from both sides:
300 - a = -160
Add a to both sides to solve for a:
a = 300 + 160
a = 460
90c = 430 - 250
Subtract 250 from both sides:
90c = 180
Divide by 90 to solve for c:
c = 180 / 90
c = 2
y 10 = 840 - 290
Subtract 290 from both sides:
y 10 = 550
Divide by 10 to solve for y:
y = 550 / 10
y = 55
Therefore, the solutions are:
a = 460
c = 2
y = 55
