4. 8y- (7y - 142) = 515. (6x + 1)-(3-2x) = 146. (6 - 2c) + 4 = - 50 - 37. (10x-3) + (14x-4) = 8 - (15 - 22x)8. (7-10k) - (8-8k) + (10k + 6) = - 89. 6 - 20 = 2(5y - 10 - 4y​

4. 8y- (7y - 142) = 51
5. (6x + 1)-(3-2x) = 14
6. (6 - 2c) + 4 = - 50 - 3
7. (10x-3) + (14x-4) = 8 - (15 - 22x)
8. (7-10k) - (8-8k) + (10k + 6) = - 8
9. 6 - 20 = 2(5y - 10 - 4y
