To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. This is:

7(2x – 3y)

= 7(2(6) – 3(-2))

= 7(12 + 6)

= 7(18)

Answer:

x = 11, y=-½

Step-by-step explanation:

Simultaneous equations - subtract the first equation from the second.

x + 4y = 9

-(x - 2y = 12)

6y = -3

y = -½

Substitute y

x + 4(-½) = 9

x + -2 = 9

x = 11

Answer:

x=3.903

Step-by-step explanation:

$2^{x-3}.5^{x-1}=200\\2^x.2^{-3}.5^x.5^{-1}=200\\\frac{2^x}{2^3}.\frac{5^x}{5^1}=200\\\frac{2^x.5^x}{2^3.5}=200\\\frac{(2.5)^x}{8.5}=200\\10^x=200 \times 40\\10^x=8000\\log 10^x=log8000\\x=\frac {log8000}{log10}=log8000=log 8\times log1000=log 8+log 1000=log2^3+log10^3=3log2+3log10=3log2+3 \approx0.903+3 \approx3.903$
