Answer:
Step-by-step explanation:
3C + 8T = 58 ----- (eq1)
5C + 2T = 23 ------(eq2)
Multiply equation (1) by 5 and equation (2) by 3
15C + 40T = 290 -----(eq3)
15C + 6T = 69 ----------(eq4)
Subtract equation (4) from (3)
34T = 221
T = 221/34
T = $6.5
Therefore 1 Table will cost $6 and 5 cents
Solve for (C) in equation (1)
3C + 8T = 58
3C + 8(6.5) = 58
3C + 52 = 58
3C = 58-52
3C = 6
C = 6/3
C = $2
1 Chair will cost $2
