➷ Double the values:
(17 : 69) x 2 = 34 : 138
Multiply both sides by 10:
(17 : 69) x 10 = 170 : 690
Triple the values:
(17 : 69) x 3 = 51 : 207

Answer:
(-21, -38)
Step-by-step explanation:
Given the simultaneous equation
10x-6y = 18 ... 1
9x+6y=39 ...2
Using the Elimination method
Subtract
10x - 9x = 18 - 39
x = -21
substitute x = -21 into 1;
From 1:
10x-6y = 18
10(-21)-6y = 18
-210 - 6y = 18
-6y = 18+210
-6y = 228
y = 228/-6
y =-38
Hence the solution to the system is (-21, -38)
