Set The Numbers On The Side Equal To The Equation. Use Inverse Operation And Divide Since The X Is Used In Multiplication.

Ok so since x is the unkown variable we would need to isolate the variable. That means do the opposite operation. So we divide 2 by 2 because thats the coefficient. Then what you do is do the same thing on the other side,divide 1 by 2 to get your answer. your answer would be x=whatever your answer is.

A) Work out the value of 5^2 – 1^5× 2^4 b) Work out the value of 7^2 + 4^3 ÷ 2^5

NemiM [27]

First you have to know BODMAS/BIDMAS (idk if all schools teach it like this) but this is the order in which you complete questions so it’s Brackets, Indices, Division/Multiplication, Addition/Subtraction
a) 5^2 is 5x5 which equals 25 1 to the power of anything is always 1 and 2^4 is 2x2x2x2 which is 16
So 5^2-1^5x2^4 = 25-1x16 which is then 25-16 = 9
b) 7^2+4^3 divided by 2^5 so 7^2 is 7x7 which = 49 then 4^3 means 4x4x4 = 64 and 2^5 is 2x2x2x2x2 which equals 32 so
7^2+4^3 divides by 2^5 is 49+64/32 = 49+2 which is 51

What is the resulting equation when the expression for y in the second equation is substituted into the first equation-3x+2y=-3

Alex

Answer:

x=-5/11, y=-9/11. (-5/11, -9/11).

Step-by-step explanation:

3x+2y=-3

y=4x+1

---------------

3x+2(4x+1)=-3

3x+8x+2=-3

11x=-3-2

11x=-5

x=-5/11

y=4(-5/11)+1

y=-20/11+11/11

y=-9/11
