Question

15) (x-84)*11=174

16) 26*y+8935=14213

17) 46*y-6435=7457

18) 1612-x=14*108

19) x-1261=17*207​

Answer 1

$15) \\ (x - 84) \times 11 = 174 \\ 11x - 924 = 174 \\ 11x = 1098 \\ x = \frac{1098}{11} = 99 \frac{9}{11}$

$17) \\ 46y - 6435 = 7457 \\ 46y = 13892 \\ y = 13892 \div 46 = 302$

$16) \\ 26y + 8935 = 14213 \\ 26y = 5278 \\ y = 5278 \div 26 = 203$

$18) \\ 1612 - x = 14 \times 108 \\ - x = - 100 \\ x = 100$

$19) \\ x - 1261 = 17 \times 207 \\ x = 3519 + 1261 = 4780$
