Question

if we subtract -3x the power of 2 y and the power of 2 from x the power of 2 y the power of 2

Answer 1

if this is your problem:[(x2y3)4(y4)0z-2]/[(xz2)3y-5] powers to a power are multiplied and multiplication of similar bases you add exponents. Any number to 0 power is 1. If a number is raised to a negative exponent, you take reciprocal. [x8y121y5]/x3z6z2 Simplifying both numerator and denominator(x8y17)/(x3z8) division you subtract exponents so finally x5y17/z8

Hope this helps you!!

Answer 2

Step-by-step explanation:

Multiplying equation (6) by 2 and subtracting (5) from it, we get

2x+4y−2x+y=9+1

∴y=2

Substituting in (5), we get

x=
