Question

x³+y²=150 find x=70 y=80​

Answer 1

Step-by-step explanation:

Solve the following simultaneous equations.

(1) 3a + 5b = 26; a + 5b = 22

(2) x + 7y = 10; 3x – 2y = 7

(3) 2x – 3y = 9; 2x + y = 13

(4) 5m – 3n = 19; m – 6n = –7

(5) 5x + 2y = –3; x + 5y = 4

(7) 99x + 101y = 499; 101x + 99y = 501

(8) 49x – 57y = 172; 57x – 49y = 252

Answer 2

Step-by-step explanation:

x³+y2=150

(70)³+(80)²=150

210+6400=150
