Answer:
2x= 3x-7
-x=-7
x=7
so, the first option
Step-by-step explanation:
Answer:
a) x^2 + y^2
b) 9-xy
Step-by-step explanation:
Here, we want to write the algebraic statements as expressions;
a) The sum of the squares of x and y
The square of x is x^2
The square of y is y^2
The sum of the squares is x^2 + y^2
ii) Product of x and y subtracted from 9
The product of x and y is x * y = xy
Subtracting these from 9, we have;
9-xy
7x-5=5x+23
7x-5x=23+5
2x=28
x=28/2
x=14
