How does keller use evidence to address the underlined counterclaim? she suggests a hypothetical situation to illustrate how dark life would be without the benefit of optimism. she uses an example from her own life to illustrate why she is able to be optimistic despite her circumstances. she explains the facts of her physical limitations to shed light on the importance of considering pessimism. she cites a quotation from an expert to lend credibility to the idea that pessimism sometimes has its merits.

the second sentence is a great revision in my opinion. that would be a great topic.

explanation:

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4

whats the question you didnt post a question
