Question

2x+2y=400,x+4=350 find x and y ​

Answer 1

Answer:

x = 346, y = -146

Step-by-step explanation:

x +4 = 350

=> x = 346

2x +2y = 400

=> x + y = 200

=> 346 +y = 200

=> y = -146

Answer 2

Answer:

x+4=350

x=350-4=346

x=346

2x+2y=400

2×346+2y=400

2y=400-692=-292

y=-292/2=-146

x=346 y=-146
