Question

solve for x and y 2^x+ 2.3^y=34, 2.2^x + 3.3^y =5​

Answer 1

Step-by-step explanation:

2^x+2.3^y=34 ----(1)

2.2^x+3.3^y=5 ----(2)

2*(1) = 2.2^x+4.3^y=68

2.2^x+3.3^y=5

- - -

0 +3^y=65

apply log on both sides

y=log65 base 3

2*(2) = 4.2^x+6.3^y=10

- - -

3*(1) = 3.2^x+6.3^y=102

2^x+0= -92

apply log on both sides

x=log (-92)base 2
